Abstract
The invention provides a flywheel system comprising a flywheel mounted for rotation within a chamber, a vacuum pump system and a valve for selectively closing a passage, wherein the chamber is coupled to an inlet of the vacuum pump system via the passage. The invention also provides a method of controlling the starting and stopping of the flywheel system.
